It really depends on what you two are looking for in a relationship, how each of them needs to be loved, and their type of personality. I'll give you two examples from my life...
Example A: My boyfriend and I dated for a year, prior to that we had worked together and chatted once in awhile online. We went on about two or three dates before we decided that we'd like to be boyfriend/girlfriend. He was a Christian, had a wonderful family and upbringing, worked hard, great sense of humor, same beliefs, yada yada yada. So why after a year of dating did we break up?
This boyfriend of mine needed to be loved a certain way, which I was happy to do.. he needed alot of space and time by himself, he needed for me to support him in what his decisions, and he wasn't very open about problems in his life (just that he wasn't brought up to communicate about his problems... which I couldn't blame him for). I needed someone who I could truly call my best friend and boyfriend, and I needed someone who could communicate with me easily, share my problems with me and share his with me, and spend a good deal of time together (not 24/7, but this boyfriend of mine I would go for months without seeing one another and days sometimes without talking). So because we had different needs (in the way of love) it didn't work out. We've only spoken a few times since breaking up, but that's probably my fault since I was the one who dumped him and now I'm dating another guy. But we did end it on good terms, so I'm happy about that... another chapter in my life closed, though I still love him because he was able to love me in his own ways.
Example B: My boyfriend (we've been dating for 4 months now) and I met on-line (actually through this site) when his roommate sent me a random pm one day saying he'd like to chat if I was bored. So we did and a few months later, Sean (my boyfriend) and I started chatting and we ended up hitting it off really well. He communicates well, very friendly and open-minded, Christian, hard worker, is getting a college education, and is close with his family.
So you see not much difference between the two guys. But what touched my heart so much is that Sean would spend time with me (although it was just chatting online or a phone call) especially if I was just by myself... Sean turned into the guy I went running to when I was upset and needed someone and over time we became best friends. So while we both understand that we should spend time apart, we love talking and hanging out, but we also make sure we both spend seperate time following hobbies and hanging out with friends.
So ya.. it really just depends on the person, the couple, and the goals of both of the people. You're still young, so your friends will contiue to meet up and break up... nothing wrong with that. This is the time where we're figuring out what kind of person we're meant to be. When you get a few years older, your friends will start to become serious and get engaged... married. For example, my best friend (who is a little younger than me... by 2 or 3 months) is already married and has a baby boy.
When you know it.. you'll know it.
